PRESS TABLE Filed Oct. l5, 1926 Patented May 13, 1930 l UNITED 1S PATENTcries ROBERT E. MANLEY, OF YORK, PENNSYLVANIA, ASS'IGNOR TO MANLEYMANUFAC- TURING COMPANY, OF YORK, PENNSYLVANIA, A CORPORATION OFDELAWARE PRESS TABLEV Application filed October 15, 1926. ySerial llo.141,848.A

lThis invention relates to presses and has for its principal object theprovision ofY a press having a table which can 'be elevated with minimumof ditl'iculty and expense into a plosition where it can be bolted tothe standart s.

A further object of the invention is the provision of means to eliminatethe heavy and also awkward counter-balancing system necessary to raisethe tables of the heavier type presses.

In garage equipment presses it is essential to have the press sufcientlysturdy to take care of any work that may be brought to it, at the sametime providing as clear a field for the work as is possible and it isalso essential that the table be so arranged that it can be elevated byone man.

The device forming the subject matter of this application provides avery simple table so constructed that a mechanic can wind both drums atthe same time, elevating the table and can hold the table suspended inapproximately the desired position by means of a pawl and ratchet andcan then by-a slight movement of the suspending chains raise theseparate ends to exact alinement for bolting.

In the drawings Figure 1 is a front elevation.

Figure' 2 is an edge elevation.

Figure 3 is a horizontal section taken just below the top iianges of thetable.

Figure 4 is a rear view of the table.

The base of the press is composed of a pair of angle irons preferablybolted to the skids 11 and also directly connected to the channelmembers 15. At the side of each channel 15 and secured thereto in aplurality of points are two bars 17 each perforated at regular intervalsas at 18 and bolted to small angle pieces 20 which are also connected tothe base angle pieces 10. Preferably the bolt 21 connecting the bars 17to the angle pieces 20 also connect the horizontal straps 22 which spaceapart the two standards and prevent their spreading at the bottom, thesestraps being tension members principally.

-At the top the four bars 17 are connected together by the usual crosspiece 25 which carries cent-rally a press 26 and at one side a smallrack press 27.v Somewhat below the cross piece 25 the two bars 17 ofeach pair are connected together by a pipe spacer 30 of theusualtype,that is, a piece of piping between the bars and a bolt passing thru thepipe and the two bars, Vthe pipe spacing the parts apart the properdistance, i. e., the overall width of the channel and the bolt holdingthe two bars together and against the pipe. rlhis structure per se iswell known and old.

lThe table consists `of two channels 33 back to back and spaced by fourpipe spacers 34 so as snugly to slide along the two standards betweenthe bolts 30 and the top of the angles 10 and is heldin place at thedesired height by Vinserting pins such as 36 in two or more of the holes38 in the channels 83 when alined with holes 18 in the bars 17.

Two square shafts 40 and 41 are rotatably mounted in the table one ateach side of the standards. The drum 44 is nonrotatably mounted on shaft40 which carries at its rear a sprocket wheel 45, va ratchet wheel 46,and a handle 47. A pawl 48 pivotally mounted on the web of the channelengages the ratchet endless chain .50,connects the sprocket wheel with asimilar sprocketwheel 52 on shaft 41, the latter `carryir'ig a drum 54exactly similar to the drum 44. y

,At the front the table carries aV guide 60 spaced somewhat away fromthe web of the channel so as to receive slidably a pair of work supports60a and 61 carrying respectively, a fixed center 62 and a movable center63, the brackets with their V-slots and centers being very convenientfor test purposes. Chains 64 and 65 are each connected to one of thebolts such as 66, which connect the standards to the vcross'p'ie'ce andare fastened at their other ends to the proximate drum whereby windingthe handle 47 will elevate the table while maintainingit constantlyparallel to the cross piece, in other words, horizontal. j l

When the table has been elevated toa point just short of the desiredposition, the handle 47 is released, the pawl 48 holding the two ends ofthe table lin position. The lmechanic thereupon lpresses in the chain 64or pulls it `wheelf46 duringelevation ofthe table. An

out, whichever is most convenient, either motion elevating the near endof the table. With his free hand the mechanic inserts-the pinsv 3G thruthe holes in the table and in the bars 1T, which are alined Vby thesideways movement of the chainfas just described.

What I claim is l. In a device of the character described, a pairostan'dards,a cross piece connecting the tops vof the standards, a tableslidable along said standards, said table consisting of two channelsarranged back to back 'and spaced apart to receive the standards, a drumcarried between the Channels 'at each side of the standards, a pawl andratchet mechanism 'for revolving both drums, avchai'n attached to eachdrumand extending diagonally to the ltop1 or` the proxirnate standard sothat by pushing or pulling on the chain in a horizon- I tal Vdirectionthe proximate end of the table is elevated, and'means for supportingthetable from the standards.

2. In a deviceof the character described, a pair of standards, a crosspiece connecting the tops of the standards, a` table'slidable along saidstandards, said table consisting of two channels arranged back to backand spaced apart toreceive the standards, a drum carried between thechannels at each side of the standards, a pawl and ratchet mechanism forrevolvingboth drums, a chain V.attached to each drum and extendingdiagonally to the top of the proximate standard so thatby pushing Lorpulling on the chain in a horizontal direction the proximate endof thetable is elevated, and a plurality of pinspassingthru alined holes inthe standards and table `for support-ing the'tabjle.

3. In V'a press table, `a pair of yvertical standards, a horizontaltable vslidalole along the standards `and extending to each `sidethereof, a drum at each end of the table outside of the' standards, andflexible means connected to the drums for raising the table on thestandards while maintaining it in horizontal position, said flexiblemeans being lo` cat edentire'ly outsideof the space between thevertical. standards.

4l. In a press table, two vertical standards each consisting of a pairotspaced rolled steel sections, a pair 'of horizontal rolled steelsections spaced apart to receive between them the two standards andforming a worlrreceiving table extending beyond the standards at eachside, and means carried by the sections outside ofthe standards Aforraising and lowering the `table while keeping it horizontal,
